[0006] The supplementary implementation plan for further improvement and optimization of the utility model is:

[0007] The inner wall of the sleeve on the fixed plate is provided with an internal thread, and the inner end of the marking rod is provided with an external thread matching the internal thread. The inner end of the marking rod can be directly inserted into the sleeve, and can also be screwed into the sleeve by a screw.

[0008] The wheel axle is made of two mutually sleeved length-adjustable pipes, and a positioning pin is arranged on the wheel axle to facilitate adjustment of the length of the wheel axle, that is, the distance between the left and right marking wheels.

[0009] The marking rods are provided with multiple groups of different lengths and multiple models, so that the distance between the color points in the lines of the section drawing can be set conveniently by using the marking rods of different lengths, thereby adjusting the distance between the steel bars.

[0010] The coloring stick is provided with an outer tube, a sponge stick is provided in the outer tube, the outer end of the sponge stick extends out of the outer end of the outer tube, and ink is injected into the outer tube. The coloring stick is extremely easy and convenient to use, and the color is clear. The outer end of the coloring stick and the line drawing rod are plug-in or threaded.

[0011] Beneficial effects of the utility model:

[0012] 1. The structure is simple and applicable, easy to make and low cost.

[0013] 2. It is easy to use and operate, which can significantly reduce labor intensity and improve efficiency.

[0014] 3. During line drawing operation, it is very convenient to adjust the distance between points and lines. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is described in detail below in conjunction with the accompanying drawings.

[0021] A steel bar spacing marking tool is provided with two marking wheels: a left marking wheel 9 and a right marking wheel 10. A horizontal wheel axle 4 is provided between the two marking wheels. The two ends of the wheel axle can be rotatably inserted into the bearings 3 arranged in the middle of the left and right marking wheels. A fixed disk 2 is fixedly provided on the outer periphery of the bearing of each marking wheel. The center of the fixed disk is a hollow disk sleeved outside the bearing. On the disk surface of the fixed disk, a circle of radially uniformly arranged sleeves 6 is fixedly provided around the hollow disk. Each of the sleeves is suitable for radially inserting a marking rod 1. The outer end of the marking rod is provided with a coloring rod 5 for marking. The inner wall of the sleeve on the fixed disk is provided with an internal thread. The inner end of the marking rod is provided with an external thread 7 matching the internal thread. The inner end of the marking rod can be directly inserted into the sleeve or screwed into the sleeve by a screw. The wheel axle is made of two mutually sleeved length-adjustable pipes, and a positioning pin 11 is provided on the wheel axle. The marking rod is provided with multiple groups of different lengths and multiple models. The coloring rod 5 is provided with an outer tube 5.1, and a sponge rod 5.2 is provided inside the outer tube. The outer end of the sponge rod extends out of the outer end of the outer tube, and ink is injected into the outer tube. The outer end of the coloring rod and the line drawing rod are plug-in or threaded. In this embodiment, the line drawing wheel, shaft rod, fixing plate, and coloring rod are all made of galvanized pipes and galvanized sheets. The components are welded and connected.
